The origin and spread of current novel coronavirus had raised serious concerns among stakeholders around the globe. Different speculations that may unfold the mystery in the future are taking roots, but now there is no globally acceptable opinion about the origin and spread of this novel coronavirus. It is reported that Wuhan city of Hubei Province of central China was the epicenter of this outbreak of novel coronavirus. However, initial inadequate preventive measures allowed the infection to cross the borders of China and that pulls the world into drastic public health and economic crisis. This coronavirus disease now named as COVID-19 by World Health Organization (WHO) and the responsible coronavirus is named as "severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)." The spread of SARS-CoV-2 is alarming even after 5 months of inception and WHO further warns the world to be prepared for more intense spread of COVID-19. Different diagnostic tools to detect SARS-CoV-2 are being used around the globe, but the identification of asymptomatic carriers of the disease is a serious challenge in countering the COVID-19 pandemic. There is no specific treatment available, only preventive, symptomatic, and supportive treatments are being used for clinical management of COVID-19. The available knowledge is limited, therefore, any escalation of information on the disease will help to combat this global challenge of COVID-19. In this review, we have discussed and summarized the available multi-factorial information and recent updates on the SARS-CoV-2 which can help support future research and may help in the strategic management of the current COVID-19 pandemic. The articles available online before June 30, 2020, on bioRxiv, medRxiv, ChemRxiv, Google Scholar, and PubMed have been assessed for the compilation of this review. Information on the official portal of WHO, CDC, ICMR, etc., were also assessed and used with due credit. [ABSTRACT FROM AUTHOR]
